We performed a comparison between DDN IntelliFlash and NetApp AFF based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."Pure Storage FlashArray's overall speed is its most valuable feature."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"It's simple, powerful, and ready to use."
"The first set up we had was really straight forward and simple."
"Access speed and power consumption are most valuable."
"The predictive performance analytics is a very good feature, as our system is performing better than before."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"It worked flawlessly."
"High performance and ease-of-management are the most valuable features."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It performed great originally, and when it performed great, it was awesome."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"Data Compression: Up to 80% space reduction in the database"
"The initial setup is straightforward."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Even though the complete workload will fill out the AFF storage box, it will give us sustained stability."
"NetApp AFF handles tier-one workloads, including home drives, departmental shares, group shares, and application shares."
"One of the main features that differentiate AFF from the FAS products, or some other technologies used, is the footprint of these arrays are significantly smaller than the traditional ones. Also, the performance that you get to these new arrays is really significant. You can see a huge difference there. By switching to it, we can achieve more storage performance and efficiency as well as in the long run lower down some of the TCOs due to reducing the footprint."
"I'm from Germany, so we have lots of metro clusters. The ability to have two sides that are redundant across hundreds or thousands of kilometers is critical for our customers. We have several hundred customers with metro cluster systems, so that is one of the best features."
"Tech support has been absolutely amazing. I think on the technical aspects as well, my staff is able to get great support from the NetApp technical support resources that we have. What I love about NetApp is they have a health care division. At times, it's such an amazing thing because if we have a healthcare-related issue, there's no one better than having prior CIOs from health care organizations that NetApp has hired, and that are part of the health care team, to help out with any of those initiatives and support problems. Support has been absolutely phenomenal."
"AFF has improved my organization because we now have better performance. We can scale up and we can create servers a lot faster now. With the storage that we had, it used to take a lot longer, but now we can provide the business what they need a lot faster."
"We are a large-scale company, and our growth has been pretty significant over the last five or six years. We like the scale, and the way NetApp grows, so that's why we use it. It's mostly for block storage."
"We have had issues before on our infrastructure where 20 to 30 percent of the people would come to us pointing the finger at the storage technology or storage back-end. That is now virtually zero."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"A three wave application or multi wave application synchronization would be an improvement."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"I would like to see a Nagios monitoring plugin which watches the health and performance of the system. The only one available just checks volume capacity."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"Snapshots are not as easy to access as on a NetApp device."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."
"It's somewhat scalable, but maybe not so much as some of the competition."
"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"The initial setup has a lot more steps in it than are probably necessary for a base deployment, unlike other vendors where it's more straightforward. It could be a little bit more streamlined."
"We'd like to see improvement in the time to retrieve from the Cloud, whether it's on-prem to cloud and whether it's public or private cloud."
"The total cost of ownership has increased a little."
"In terms of improvement, IO performance could use some enhancement."
"In terms of improvement, the support could be a little better."
"I would like them to roll in global monitoring instead of having to buy another product for it."
"Implementation needs to be improved."
"I would like to see NetApp improve more of its offline tools and utilities."
